Global Server Load Balancing
Secure DNS Resolution and Intelligent Traffic Routing for Multi-Data Centers
In multi-data center and hybrid cloud setups, IT teams face many challenges: higher chances of outages, slower access for users because of network differences, and difficulty tracking the real health of services. At the same time, DDoS attacks and DNS tunneling threats are growing, while sudden or unusual traffic spikes can overload core network services. Moving workloads across different platforms may also cause instability. All of this puts service availability at risk, leading to downtime, data leaks, user loss, and rising operational costs.
Yamu GSLB is a DNS security and smart traffic management system built for multi–data center environments. It provides a safe, reliable, and easy-to-manage DNS service with high availability and intelligent traffic control. With its strong architecture and smart scheduling, Yamu GSLB helps companies protect the network edge, keep services running without interruption, improve security, and deliver better performance in complex networks.

Ensure uninterrupted DNS service with carrier-grade protection.
Optimize traffic delivery with topology-aware routing, smart load balancing and real-time health monitoring to ensure seamless fail-over.
Enhance operational efficiency with rich APIs, bulk management tools, and GUI.

Yamu GSLB uses high-performance, carrier-grade security to block DDoS attacks and sudden traffic spikes right at the DNS entry point. Malicious requests are detected and filtered in real time, keeping DNS services stable and secure.

With built-in health checks and smart fail-over, Yamu GSLB quickly switches traffic away from failed links or services. This minimizes downtime and ensures that critical applications stay online and accessible.

Yamu GSLB supports mixed DNS environments and automates configuration updates, making it easier to migrate without service interruptions. It reduces complexity and keeps systems compatible and under control during transitions.

The system continuously monitors DNS traffic and performance. Logs and metrics are analyzed in real time, and if issues appear, automatic diagnosis and recovery steps are triggered to keep services reliable.

With accurate IP database and smart traffic rules, Yamu GSLB routes users to the nearest or best-performing node. This reduces delays and improves connection quality, giving users faster and smoother experiences.

The central management console supports automated checks, workflow approvals, batch changes, and fine-grained access control. Combined with full API support, this reduces manual work and speeds up daily operations.

Yamu GSLB handles high traffic at line speed and can add new nodes on demand. Capacity expands smoothly without redesigning the network, ensuring DNS services grow in step with your business needs.
